ble to large-mouth vessels or bottles.

An object of the invention-is to provide an exceedingly edective and simple yet economical sealing device which will maintain a tight seal and can be easily and quickly opened.

The invention consists in certain novel features in construction and in combinations of vparts, as more fully and particularly explained and pointed out hereinafter.

Referring to the accompanying drawings,

which merely show one form of my invention as an example for purposes of explanation from among other forms within the spirit and scope of my invention, Figure 1 is a perspective view of a jar or large-mouth bottle or receptacle to which my improved seal has been.

applied, the seal being shown brokenand opened to permit-access to the interior or contents o the jar, an advertising paper sheet being shown on the sealing-disk. Fig. 2 isa vertical sectional view, through the mouth portion of the jar, the seal being shown applied, an outside cap being shown, the advertising sheet of paper not being shown. Fig. 3 is a perspective of the mouth portion of the jar, showing the seal applied to tightly close and seal the jar, the advertising paper sheet not being shown. Fig. 4 is a perspective view showing the mouth portion of the jar,the compressible impervious sealingdisk, the cylindrical locking-cap before being spun or turned under, and the advertising paper sheet, said parts being shown separated. Fig. 5 is a perspective view showing a cap and sealing-disk separated from the jar-mouth,

the sealing-disk being partially broken away anda modified arrangement of cap and jarmouth being shown.

In thedrawings, ct is a bottle, jar, ory other y receptacle, the specific example being illustrated as a large-mouth bottle or jar. The' jar can be of any suitable and desirable construction, having a mouth-opening surrounded by the annular top edge b and an exterior annular flange or shoulderc a distance below the top edge b,the exterior of the bottle-'mouth between the shoulder c and top edge b being usually cylindrical, although I do not wish to so limit my invention. be formed in any suitable manner and of various configurations to coact With vthe sealing-disk in increasing the tightness of the' seal or joint, and hence I do not Wish to limit my invention to the topedge b with the Hat face, as shown.

CZ is an imperfo'rate dat disk, of impervious or waterproof yet soft and compressible material whichcan be easily and quickly perfo'- rated and cut or severed with a light thin blade or by the application of slight force to anysuitable instrumentforpunchingthrough or perforating and then cutting. o r severing the disk. I prefer to form the disk of a thick yheavy soft compressible paper fabric treated with suitable materials or substances which f soak into the fabric and render the sameimpervious to moisture and air Without so hardening the fabric as to render the same inca'- pable of being compressed to form and main.-

` tain a tight seal and permit easy puncturingV` and severing of the disk. I have discovered =that thicker heavy soft commercial blottingpaper can be so treated as to render the same impervious without destroying'the peculiark qualities of softness and the ease with which lsuch paper fabric can be severed or torn. -Blotting-paper so treated can be produced very economically and yet attains superior and exceedingly advantageous results when- The top edge b can n employed as a compressible sealing-disk. A

seal employing s'uch blotting-paper as a sealing medium can be produced at a minimum cost and yet attains certain material new results or advantages. I employ the term blotting-paper herein in a broad sense to inf clude soft or compressible paper treated to `render the same impervious and theequivalents thereof. k

The blotting-paper sealing-disk d is shown of a diameter approximately equal to the exroo ternal diameter of the top or sealing edge b of the jar-mouth, on which the under face of the flat disk rests, the disk completely spanning, covering, and closing the mouth or top of the jar. Suitable devices or means are employed to press the disk down on the top edge of the jar-mouth to maintain the seal and hold and lock the disk and preferably to eX- pose the central portion of the disk to display a separate advertising-sheet or to permit a blade or other instrument being forced through the disk and then moved around the inner surface or circle of the jar-mouth to sever or cut out or partially cut around the exposed portion of the disk, thereby breaking the seal and opening the jar. As an eX- ample which can be employed for this purpose I show a locking-cap e, having its center cut out to form the annular top horizontal flange and the depending cylindrical portion. This cap is formed of suitable ductile or non-spring thin sheet metal, and the cylindrical portion thereof is ot' such diameter as to snugly fit the exterior cylindrical portion of the jar-mouth between the top edge b and shoulder c, and the said depending cylindrical (or otherwise-shaped vertical) portion of the cap is of greater length than the distance from the shoulder c to the top edge b. The top flange of the cap is preferably radially as wide as or greater in width radially than the top edge b, so that the inner circle of said flange will he above and not of less diameter than the circle of the inner edge of the top edge h.

In applying the sealing device the compressible disk can he forced or slipped into the cap until it rests against the dat under face of the top flange ofthe cap. The cap is then slipped onto the exterior of the bottlemouth until the disk rests on the top edge b. The necessary pressure can then be applied to the top flange of the cap and directly over the top edge b to force down the cap and compress the disk d to the desired degree between top edge Z2 and the top flange of the cap. Vhile the cap is thus held down compressing the disk the lower end of the cap, projecting below the plane of shoulder c, can be spun or otherwise turned in tightly under said shoulder to permanently (or otherwise) fasten the cap on the jar-mouth and to maintain the disk tightly compressed between the cap-liange and top edge b, forming the tight seal. If desired, the cap can be otherwise fastened to the jar or can be removable and otherwise fastened and drawn down to compress the disk. For instance, in Fig. 5 I show the jar-mouth formed with external vertical slots or notchesf, with theunder edges of the rim between the notches inclined to form cams or inclines g. The cap is shown at its lower end formed with inwardly-projecting radial lugs 7L, spaced to pass down through notches f as the cap is slipped onto the jar-mouth and to move under the inclines g and draw the cap down Whenthe same is moved axially on the jar, as will be readily understood by those skilled in the art.

If desired, advertising matter can be imprinted on a circular sheet or disk of paper il, (see Figs. l and 4,) and such disk can be loosely placed on the disk d, so as to be held or clamped between the sealing disk and llange of the cap, leaving the advertising matter exposed at the open top or center of the cap. Also, if desired, an outside imperforate sheetmetal or other cap j can be slipped over the mouth of the jar when sealed, as shown in Fig. 2. Such cap would fit down on the vertical portion of cap e and cover the top thereof and the disk and be held in place by friction. Such cover or exterior cap might be used to protect the paper advertising sheet hereinbefore mentioned and the sealing-disk where the jars are to be steamed after filling and sealing. However, I do not wish to limit myself to the employment of the advertising-sheet nor the eXterior cap, although advantages are attained in my combination by employing the paper advertising-sheet.

The nature of the impervious blotting-paper disk is such that a small blade or other pointed instrument can be very easily pushed through the disk and moved around the inner edge ofthe cap,using the same as a guide, to cut out or sever the central portion of the disk. The central portion of the disk can he out complet-ely out to open the jar or can be cut partially around and turned up, as shown in Fig. l, and then turned down to again close the opening, and thus serve as a cover to protect any material which may remain in the jar.

In the construction shown in Figs. l to 4 the cap e remains on the jar after the breaking of the seal, the cap being usually drawn in one continuous piece and non-severable, although my invention is not so limited.

The blotting-paper disk is usually tightly compressed against the inner surface of the cylindrical portion of the cap and down over theinner edge of the top of the bottle-mouth, as well as between the flange of the cap and the top edge of the bottle-mouth, so that the sealing-disk is laterally as well as vertically compressed and the jar is sealed along different lines or points.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A sealing device comprising a cap, in combination with the sealing means adapted to be held compressed by the cap to maintain a tight seal and composed of the compressible impervious paper or fabric, substantially as described.

2. A sealing device comprising a sealingdisk of compressible paper treated to render the same impervious, and means for locking and maintaining said disk compressed against the sealing edge of a bottle or jar and effecting the tight seal, substantially as described.

3. A sealing device comprising an imperferate impervious sheet 4of compressible readily punctured and severed paper,l and means for locking and holding said sheet against the topvedge of the jar-mouth to cover and close said month and maintain a tightl seal, saidk means exposing the central portion of said sheet so that the sheet can be cut around said and a cap having a depending annularange l within which said sheet is frictionally held and which is locked under said exterior holding means to hold down the cap maintaining the seal, said cap having the top annular horizontal flange bearing down on the portion of the sheet over said .top edge and leavingv the remainder of the sheet exposed to permit passage therethrough of a cutting instrument for severing the sheet around the inner edge of said flange, substantially as described.

5. A jar having a top sealing edge around its mouth and an exterior annular lockingshonlder below said top edge, in combination withV a sheet of compressible impervious pa-L per fabric covering the jar-mouth and resting on said top edge,

a depending annular dan ge permanently spun under said shoulder while the cap is held down under pressure to compress said sheet against said edge to form the tight seal, said cap having the lateral annular top flange and a metal cap havingV above the said edge and said sheet, the said cap being open within said ange to permit puncturing and cutting the sheet to open the jar independently of the cap, as described.

6. A receptacle havinga top annular seal-y ing edge around its mouth and an exterior locking-shoulder below said edge, in combination with a flexible imperforate sheet of impervious compressible paper fabric closing the mouth of the receptacle and resting substantially on said edge, and a metal locking-cap having an exterior depending annular flange engaging said shoulder to lock the cap compressing said sheet, said cap having the lateral annular top iange above and compressing said sheet and forming the central top opening of the cap approximately of the same diameter as the internal diameter of the mouth of the receptacle whereby the inne-r surface of the mouth of the receptacle can form a guide for the cutting instrument when passed through said sheet and cutting the exposed center thereof, substantially as described.-

7. A jar-seal comprising a cylindrical metal cap having an annular top flange forming the top opening, an imperforate sheet of cornpressible impervious fitted in said cap and against said flange, and the imperforate exterior' cover removably fitted over the end of said cap and covering the exposed portion of said sheet, substantially.

as described.

In testimony whereof I affix my signature in presence of two witnesses.
